The reliability of in-depth curvature judgements for linear elements was studied with stereograms that contained two linear targets and a background representing a hemisphere. The targets were arcs facing to the left or to the right, like parentheses. Some formed binocular pairs with (type 1) or without (type 2) in-depth curvature. The others were monocular (type 3). The hemisphere in the background was generated by a random curve (Ninio, 1981 Perception10 403 – 410); it was either concave (hollow) or convex. The arcs had their binocular centre in the plane of the centre of the hemisphere. Each stereogram contained a type 1, and either a type 2 or a type 3 target. Subjects had to judge the hemisphere curvature, then the in-depth curvature of the targets in 32 different stereograms covering all curvature combinations. There were about 15% errors on type 1 targets, and 80% of these occurred when both the hemisphere and the target were convex, the target being perceived as concave, by transparency through the hemisphere. There were also about 15% errors on type 2 targets, but spread among all situations, the trend being to perceive them as slightly concave. The monocular stimuli (type 3) were judged to be frontoparallel in 70% of the cases. Otherwise, there was no directional bias except for monocular arcs on the nasal side, in conjunction with a concave background. Then, the perceived in-depth curvature was in the ‘generic’ direction predicted by associating the monocular arc in one image with a straight vertical segment in the other image.

The Relationship

This study attempts to analyze to what extent governance and sustainable development (SD) empirically appear compatible in the thirtyfive OECD countries through the fuzzy-set ideal type analysis, and identify which ideal types appear coupled or decoupled, and then reveal which countries belong to the coupled types or to the decoupled types. In short, twenty-two countries (including Sweden (fuzzy score, 0.953), Denmark (0.920), Finland (0.914), Norway (0.911) in Type 1 (G*S, ‘strong G-S coupled countries’); and Turkey (0.906), Greece (0.833), Mexico (0.828) in Type 4 (g*s, ‘lite g-s coupled countries’) are in line with the accepted conventions regarding the compatible relationship between governance and SD. On the other hand, the rest of thirteen countries (including USA (fuzzy score, 0.815), Luxembourg (0.721), Australia (0.660) in Type 2 (G*s, ‘G-s decoupled countries’); and Slovenia (0.728), France (0.644), Czech Rep. (0.625) in Type 3 (g*S, ‘g-S decoupled countries’) may indicate that the relationship of governance and SD is in fact experiencing tensions in the national contexts. These findings are characterized by the substance (of SD) and procedure (of governance) divide. Considering the results, this study focuses on the idea of reflexivity or reflexive capacity.

Carburetor modification to the venturi mixer to put a hole in the center of the venturi (end of hole venturi type nozzle on the outlet end venturi section) can turn the engine generator using biogas fuel. Airflow velocity carburetor venturi section will begin upon entering the venturi section and will be maximal at the time in the middle of the venturi section. So of course the location of the placement of venturi carburetor venturi mixer on the right cross section will be obtained velocity airflow + optimum biogas. It is necessary for optimizing the placement location of the modification of the carburetor venturi mixer, air flow + in order to obtain optimum biogas which will have implications for the performance of the generator engine. In this research, manufacture three prototypes nozzle venturi mixer that will be placed at different places in the venturi duct, then the performance test was done to determine the type and location of the venturi nozzle prototype mixer is optimal. From the results of this study that : 1) Prototype nozzle venturi mixer with the tip of the nozzle in the middle (shape elbow) has the most complicated construction than the second type (type 1 and 2) the other. Manufacturing and assembly to form the elbow (type 3) is also more complicated and more difficult , this is because the space available / remaining biogas is limited to hole channel, and 2) Using a prototype generator machine type 3 is more stable when compared with other types, despite the decline, but not very significant in comparison with the other 2 types, so the prototype mixer venturi nozzle is the most optimal type 3 (square shape).

The government through the Ministry of Marine and Fisheries offers assistance of fishing vessel to achieve fisheries production targets. This procurement plan must be supported by the ability and selection of the right shipyard. Beacuse the information of the capability and capacity of fiber shipyards in Indonesia is unclear, so the realization of the procurement of fishing vessel in previous years did not met the planned targets. The purpose of this study was to analyze shipyard capacity to meet the planned procurement of KKP fishing vessels grant in 2019. First classification of fishing vessels is based on the size of each GT, which is 5 GT (type 1), 5-10 GT (type 2), and 20-30 GT (type 3). The second is the minimum shipyard criteria for building fishing boats. Third, an assessment of the shipyard is based on the criteria that have been made. Fourth, shipyard selection was carried out on each WPPN-RI using the load score method. The fifth calculates the number of ships that can be built by the shipyard. The results of the shipyard assessment found that 43% of shipyards have the ability to build type 1 vessels, around 38% of shipyards have the ability to build type 2 vessels, and around 19% of shipyards have the ability to build type 3 vessels. is 1625 units / period. Referring to shipyard capacity, it can be said that the entire shipyard is able to fulfill the plan to procure assistance for KKP fishing vessels in the 2019 budget year.

Endometrial adenocarcinoma in women under the age of forty presents a different course according to its histology. Adenocarcinomas of the endometrium may be classified into 4 main types: type 1, homologous or endometrioid; type 2, fallopian-like; type 3, cervical-like; type 4, unclassifiable. The majority of homologous adenocarcinomas have a relatively benign course, whereas the other types are definitely malignant. There is no room for doubt between adenocarcinoma and atypical endometrial hyperplasia in women under forty unless the histological pattern is of the homologous or endometrioid type, because the other patterns are definitely malignant.

Finger Length Ratio

This study aimed to evaluate the association between the index to ring (2D:4D) finger length ratio and aging-related traits (hand osteoarthritis (OA), the osseographic score (OSS), and reproductive period), as well as to assess the heritability of finger length. A Chuvashian population-based sample included 802 males (mean age 46.98±17.10 years) and 738 females (mean age 48.65±16.62 years). Age, sex, basic demographics, anthropometric data, reproductive indices (age at menarche, menopausal age, and length of the reproductive period), and x-rays of both hands were collected. Finger length ratio was measured on x-ray and each hand was visually classified as either type 1 – 2D>4D; type 2 ― 2D=4D; or type 3 ― 2D<4D. Hand OA was defined by the number of affected joints (Kellgren-Lawrence score ≥2) and the total of Kellgren-Lawrence scores (total OA score). OSS is a skeletal biomarker that comprises osteoporotic and OA changes observable on a hands x-ray. We calculated the familial correlations and performed a heritability analysis of 2D:4D ratio traits in a studied sample. After comparing the OA variables of individuals with different finger length ratio types (after adjustment for age and BMI) significant differences were found only in females between finger ratio types of the right hand in a number of affected joints (F=3.153, p=0. 043) and finger ratio types of the left (F=3.330, p=0. 036) and right (F=2.397, p=0. 047) hands of the total OA score. Females with type 3 ratio had the highest adjusted values of hand OA parameters. Results of one-way ANCOVA for finger length ratio types of the right hand showed a significant difference in OSS (df =2, F=7.569, P=0.001), after adjustment for age, sex, and BMI. The posthoc comparison showed that individuals with type 3 (2D<4D) ratio showed significantly higher OSS scores than ones with type 1 (p=0.012) and type 2 (p=0.003). In an analysis of finger length ratio types of left hand also a significant difference in OSS was found (df=2, F=3.290, P=0.038). The posthoc comparison showed that individuals with type 3 ratio showed significantly higher OSS scores than ones with type 2 (p=0.33) ratio. We found that a low finger length ratio, a masculine visually evaluated finger length ratio type, was associated with later menarche and a shorter reproductive period. No association was found with menopausal age. Familial correlations of finger length ratio traits showed no significant correlation for spouses, however, parent-offspring (0.15―0.28, p<0.001) and sibling correlations (0.13―0.38, p<0.009) were found significant. Heritability (H2) of visual classification of finger length ratio was 0.36 for the left and 0.28 for the right hand; finger ratio was 0.55 and 0.66, respectively; the ray ratio was 0.49 and 0.59, respectively, thus indicating the existence of a clear familial aggregation of finger length ratio variation in the Chuvashian pedigrees, which cannot be explained by pure common environmental effects.

Regional Grouping

Soil fertility patterns in the wheatgrowing areas of Victoria were examined. The three major patterns identified from the protein content of wheat delivered to 113 silos over the period 1946-74 showed a marked regional grouping encompassing the Wimmera (type 3), Western Mallee (type 2) and the Eastern Mallee, Northern and North-East Districts (type 1). Using 107 P x N wheat fertilizer experiments, four major patterns were identified. Only one of these (low P, nil N yield response) showed any regional grouping (with the Wimmera region); the other three (moderate P, moderate N; high P, small N ; and high P, nil N yield responses) occurred at random throughout the wheat belt. Possible reasons for these patterns and their implications are discussed.

Anaerobic reactions of Rhus vernicifera laccase and its type-2 copper-depleted derivatives with hexacyanoferrate(II) were investigated by absorption and e.s.r. spectroscopy. When native laccase was treated with excess hexacyanoferrate(II), the type-1 and type-2 coppers were immediately reduced and the e.s.r. signal due to type-3 copper was transiently observed. After incubation, a novel e.s.r. signal (g parallel = 2.31, g perpendicular = 2.08) developed together with the type-1 copper signal. Only the novel e.s.r. signal was left after the sample had been treated with ascorbate. In the corresponding absorption spectrum, a new band was observed at around 490 nm. A similar new e.s.r. signal did not appear for the type-2-copper-depleted (T2D) laccase, in which the type-3 copper had been reduced during the procedure to deplete the type-2 copper. On the other hand, the novel e.s.r. signal emerged when the type-3 copper in T2D laccase had been previously reoxidized with H2O2. The novel e.s.r. signal was not significantly saturated even by 200 mV microwave power at 4 K. Quantitative estimations and a small molecule study for CuII-FeII(CN)6 and CuII-FeIII(CN)6 systems suggested that the novel e.s.r. signal corresponds to some sort of adduct involving the type-3 copper and hexacyanoferrate(II).

Mennickent et al. (2002) presented a catalogue of 1056 Be star candidates in the Small Magellanic cloud (SMC) by studying light curve variation using OGLE II data base. They classified these Be star candidates of the SMC in four categories: Type 1 stars showing outbursts (139 stars); Type 2 stars showing sudden luminosity jumps (154 stars); Type 3 stars showing periodic or near periodic variations (78 stars); Type 4 stars showing light curves similar to Galactic Be stars (658 stars). They suggested that Type 4 could be Be stars. On the other hand, they suggested that Type-3 stars may not be linked to the Be star phenomenon at all.

In a character-judgment paradigm, the subject quickly pressed a key when a hiragana (Japanese syllabary) appeared on a display and did nothing when a kanji (Japanese logograph) appeared. The amplitude of the N400 component was compared when four types of visual stimuli were used: (Type 1) single kanji—Grade 1- to 3-level words, (Type 2) single kanji—Grade 1- to 3-level bound morphemes, (Type 3) single kanji—high school- and college-level bound morphemes, and (Type 4) obsolete kanji. Analysis showed that N400 was largest in the temporal-occipital areas for the Type 1 stimuli and larger in the right parietal area for Type 2 than Type 3 stimuli. The analyses of N400 to semantic stimulations have been conducted and discussed in terms of their meaningfulness, age when writing of these kanji was mastered, and linguistic status (kanji versus nonkanji). Most interestingly, the Types 3 and 4 kanji did not activate semantic responses, showing that they did not function as linguistic units, i.e., kanji, in the mental lexicon.

The assessment and dynamic control over students’ status is a very important task. It allows timely detection of prenosological status prior to pathology and health maintenance in students. The objective of the paper is to assess the adaptive abilities of the body, to analyze changes in heart rate variability indicators in students with various types of autonomic regulation, to identify prenosological status and precursory pathological symptoms. Materials and Methods. The study enrolled 302 students from India, aged 21.54±1.43. Programming complex «Psychophysiologist» was used to register the main HRV parameters within 5 minutes. Health status was evaluated according to the index of functional changes and the scale of functional states. Results. N.I. Shlyk (2009) distinguished two groups of students with different types of autonomic regulation: type 1 (53 %) with moderate and type 2 (5 %) with marked characteristics of central regulation profile, type 3 (35 %) with moderate and type 4 (7 %) with marked characteristics of autonomous regulation profile. Main parameters of HRV and adaptation potential were defined for each student.All the parameters characterized functional and health status. Conclusions. It was shown that 82 % of trial subjects (type 1), 53 % (type 2), 94 % (type 3) and 95 % (type 4) demonstrated satisfactory adaptation and their physiological processes were at an optimal level. 18 % of students (type 1) demonstrated reduced adaptive abilities of the body. Moreover, they were under moderate stress. 47 % of subjects (type 2) were also under a significant stress, which was proven by excessively high SI, low SDNN and TP, and an increased index of functional changes. 5 % of students (type 4) revealed dysfunctional characteristics in the heart rhythm, peculiar to pathology. Keywords: foreign students, heart rate variability, types of autonomic regulation, adaptation potential, functional status. Оценка состояния студентов и динамический контроль за ним является важной задачей, поскольку позволяет своевременно выявлять у студентов донозологические состояния, предшествующие патологии, и способствовать сохранению здоровья. Цель. Оценка адаптивных возможностей организма, анализ изменений показателей вариабельности сердечного ритма у студентов с различными типами вегетативной регуляции, выявление донозологических состояний и ранних признаков патологии. Материалы и методы. В исследовании участвовало 302 студента в возрасте 21,54+1,43 года из Индии. Регистрировались основные параметры ВСР в течение 5 мин с использованием программно-аппаратного комплекса «Психофизиолог». Состояние и уровень здоровья оценивались по индексу функциональных изменений и шкале функциональных состояний. Результаты. По способу, предложенному Н.И. Шлык, выделены группы студентов с различными типами вегетативной регуляции: I (53 %) и II типы (5 %) – с умеренным и выраженным преобладанием центрального контура регуляции соответственно, III (35 %) и IV типы (7 %) – с умеренным и выраженным преобладанием автономного контура регуляции соответственно. У каждого из студентов определены основные параметры ВСР и адаптационного потенциала, характеризующие функциональное состояние и уровень здоровья. Выводы. Показано, что для 82 % обследуемых с I типом, 53 % со II типом, 94 % c III типом и 95 % с IV типом регуляции характерно состояние удовлетворительной адаптации, физиологические процессы сохраняются на оптимальном уровне. В группе студентов I типа у 18 % студентов адаптивные возможности организма снижены, выявлено состояние умеренного напряжения. У 47 % обследуемых II типа также зафиксировано состояние резко выраженного напряжения, индикатором которого является чрезмерно высокое значение SI, низкие величины SDNN и ТP, повышенное значение индекса функциональных изменений. В группе студентов с IV типом у 5 % учащихсяв регуляции ритма сердца выявлены дисфункциональные признаки, характерные для патологии. Ключевые слова: иностранные студенты, вариабельность сердечного ритма, типы вегетативной регуляции, адаптационный потенциал, функциональное состояние.
